A​re F1 And IndyCar Becoming Too Similar?

It seems that the 2021 F1 car is finally taking shape, as today, the very first photos have been released, along with details of the new car. The car looks sensational, and according to F1, is a total success in terms of reducing dirty air, but there's one problem: it isn't really an F1 car. It's more of an IndyCar than anything else.

H​ear me out.

L​et's start with what the main differences between F1 and IndyCar are:

1​. Aerodynamic complexity- F1 has always had intricate aerodynamics, but in 2021, the pinnacle of motorsport will be stepping back and making the aero simpler, in the name of closer racing.

2​. Hybrid power units- Since 2009, F1 has had electric power play some sort of a role in powering the cars. This has always been a key difference between the two series. However, in 2022, Indycar will also be moving to hybrid V6 units.

3​. Spec parts- while F1 is constantly in a race to develop tech faster, IndyCar gets a large number of parts given to them from Dallara and their respective engine manufacturers. This is still a key difference between the two series, but it's a distinction that will have less meaning in 2021, as F1 begins to put some spec parts into their cars.

4​. It used to be that Indycars were heavier and larger, but now, with F1 cars growing rapidly, the cars are roughly the same in dimensions, and weight.

To boil it down to one rule, the difference was, Indycar has always been for entertainment. F1 has always been for technological advancements.

B​ut this isn't true anymore. It seems F1 has taken the route of entertainment, so as a result, there are only minor differences between F1 and its American single-seater counterpart.

F​1 and IndyCar have always been alike, but never to this extent. They are certainly becoming more and more similar, the question is; who's copying who?
